Used as an antioxidant and stabilizer in polymers and rubber products. It protects materials from degradation caused by heat, light, and oxygen, extending the lifespan of plastic and elastomer-based items. Commonly found in automotive rubber parts, cables, and industrial hoses where thermal stability is critical. Also serves as an intermediate in the synthesis of dyes and pigments due to its aromatic amine structure. Its sterically hindered structure enhances performance in high-temperature processing.
